Question

For intervals of values, enter your answer using interval notation. Here are some examples of how interval notation relates to inequalities: With inequalities, we use "less than": to exclude the endpoint of the interval. With interval notation, we use use round parentheses, (or). With inequalities, we use "less than or equal to": lessthanorequalto or "greater than or equal to": Greaterthanorequalto to include the endpoint of the interval. With interval notation, we use use square brackets, [or]. To combine two intervals, use U (an uppercase letter u) for union: U Use oo (two lowercase letter o's) for infinity: infinity For example, to enter (-infinity, - 2] U (3, 6], you would type: (-oo, -2]U(3, 6] Try it now. Enter the interval equivalent to 2 7

Explanation / Answer

2 < x <= 5 or x > 7

OR means union

Notice that 2 is not included
But 5 is

So, 2 < x <= 5 is written as
(2 , 5]

x > 7 means 7 is not included

x > 7 is written as (7 , infinity)

With a union in the middle because of the "OR"

So, final answer :

(2 , 5] U (7 , inf) -----> ANSWER
